Hmm. I wonder if this would make a great difference
upgraded z motor.
already using ball screws.
its basically the MDF insulator but in aluminum to be printed upon. and the insulator made smaller.
MDF no longer an influence on the thin aluminum
Mic6 is the most even expanding
4 corners changed to SHCS from FH.
Should make for a more stable bed. being now that the MDF wont expand and contract all weird.
ive got/had 2 aluminum beds for the herc both have been influenced by the MDF insulator.
if the hammer doesnt work…get the bigger hammer.
i present. the bigger hammer.
also looking at either using smoothie or upgrading to trinamic drivers ( the ones in the prusa?) for the z axis i may need a higher amp driver. due to the possibly more torquey motor needed
i will be needing a little help in choosing a stepper. as i dont know if holding torque ratings translate well to the rotational torque. or if the holding torque is 100% different.
as i understand it. holding torque is the force required to move the motor shaft when it is idle at a position. ie the force needed to make it skip a step
oh and the engraving is at the rear for the edge where the silicon bed wires come out. and i figured why not engrave a line for the “printable” area too.
may mill out a recess later for a bed material like printbite etc. so it lats flush. not 100% on that idea. as it means sticking with a adhesion medium. and i dont like the idea of being confined.
May also remove the “safe zone” engraving and try to figure out where a “prime area” could be
i bet this looks like rambling. wow this type window is tiny!
